PC won't start after a BIOS update

Hello, I updated the BIOS via the Dragon Center software for my MSI H310M Pro-D motherboard

The update went to 100%, the computer was supposed to restart... But it never did, and since then it has been off.

I tried removing the battery for more than 20 minutes (about ten times) and pressing the power button for 30 seconds.

It didn't do anything

I then tried the CMOS (I don't have a jumper) so I tried to connect the two metal bars for several seconds with a flat screwdriver.

That didn't work either.

Finally, I removed both RAM sticks.

Nothing more.

When the computer is plugged in and I spam the power button, sometimes it lights up for 1 second, just long enough to turn on the fans, then it turns off immediately after.

Do you have a solution?

Hello,
Yet according to your card's manual, there is a jumper to move:
JBAT1: Clear CMOS (Reset BIOS) Jumper
There is CMOS memory onboard that is externally powered from a battery located on
the motherboard to save system configuration data. If you want to clear the system
configuration, set the jumper to clear the CMOS memory.
Keep Data
(default)
Clear CMOS/ Reset
BIOS
Resetting BIOS to default values
1. Power off the computer and unplug the power cord.
2. Use a jumper cap to short JBAT1 for about 5-10 seconds.
3. Remove the jumper cap from JBAT1.
4. Plug the power cord and power on the computer.

It is located at the bottom left of the battery.

See you later.

OK, but can we put one on or make contact with a screwdriver? Are there any pins?

I tried to connect the two pins with a screwdriver, a knife, and a paperclip, but none worked.

This procedure:
BIOS Update:
1. Insert the USB stick containing the update file into the computer.
2. Press the <ctrl f5=""> key during POST (startup).
3. Click Yes to restart the system and enter flash mode.
4. Select a BIOS file to execute the BIOS update process.
5. Once the flashing process is 100% complete, the system will restart
automatically.
What version of BIOS did you try to install, this one seems to have proven itself: 7B33v1B ??

See you later.</ctrl>

Hello,

I have exactly the same problem. I updated my motherboard with Dragon and I get "no signal" and I can't even access the Windows interface anymore.

Did you find a solution to help me?
That would be really nice.

I finally took my PC to a repairman, and according to him, the motherboard is dead, so he's going to replace it.
